♦ 10pC (max) Charge Injection
The MAX4526/MAX4527 are CMOS analog ICs config-
ure d a s p ha s e -re ve rs a l s witc he s . The MAX4526 is
optimized for high-speed applications, such as chop-
p e r a mp lifie rs , while the MAX4527 is op timize d for
low-power applications.
♦ 2pC (max) Charge-Injection Match
♦ 175Ω Signal Paths with ±15V Supplies
♦ Guaranteed Break-Before-Make
The MAX4526/MAX4527 operate from a +4.5V to +36V
single supply or ±4.5V to ±18V dual supplies. On-resis-
tance (175Ω max) is matched between switches to 8Ω
maximum. Each switch can handle rail-to-rail analog
signals. Maximum leakage current is only 0.5nA at
+25°C and 10nA at +85°C.
♦ Rail-to-Rail Signal Handling
♦ Transition Time < 100ns with ±15V Supplies
♦ 1µA Current Consumption (MAX4527)
♦ >2kV ESD Protection per Method 3015.7
♦ TTL/CMOS-Compatible Inputs
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility.
♦ Available in Small, 8-Pin µMAX Package

The MAX4526/MAX4527 are phase-reversal analog
switches, consisting of two normally open and two nor-
mally closed CMOS analog switches arranged in a
bridge configuration. Analog signals are put into two
input pins and taken out of two output pins. A logic-
level signal controls whether the input signal is routed
through normally or inverted. A low-resistance DC path
goes from inputs to outputs at all times, yet isolation
between the two signal paths is excellent. Analog sig-
nals range from V- to V+.

These parts are characterized and optimized with ±15V
supplies, and they can operate from a single supply.
The MAX4526 is optimized for high-frequency opera-
tion, and has a higher-speed logic-level translator and

characteristics, but has a slower logic-level translator
and switch driver for lower current consumption.

The MAX4526/MAX4527 are designed for DC and low-

chopper amplifiers, modulator/demodulators, and self-
zeroing or self-calibrating circuits. Unlike conventional
CMOS switches externally wired in a bridge configura-
tion, both DC and AC symmetry are optimized with a
small 8-pin configuration that allows simple board lay-
out and isolation of logic signals from analog signals.

Bipolar Supplies
The MAX4526/MAX4527 operate with bipolar supplies
between ±4.5V and ±18V. However, since all factory
characterization is done with ±15V supplies, specifica-
tions at other supplies are not guaranteed. The V+ and
V- supplies need not be symmetrical, but their sum
cannot exceed the absolute maximum rating of 44V
(see Absolute Maximum Ratings).
P o w e r-S u p p ly Co n s id e ra t io n s
Overview
The MAX4526/MAX4527 construction is typical of most
CMOS analog switches. It has three supply pins: V+, V-,
and GND. V+ and V- drive the internal CMOS switches
a nd s e t the a na log -volta g e limits on a ny s witc h.
Reverse ESD-protection diodes are internally connect-
ed between each analog signal pin, and both V+ and
V-. One of these diodes conducts if any analog signal
exceeds V+ or V-.
Virtually all of the analog leakage current is through the
ESD diodes to V+ or V-. Although the ESD diodes on a
given signal pin are identical and therefore fairly well
balanced, they are reverse biased differently. Each is
biased by either V+ or V- and the analog signal. This
means their leakages vary as the signal varies. The dif-
ference in the two diode leakages from the signal path
to the V+ and V- pins constitutes the analog-signal-path
leakage current. All analog leakage current flows to the
supply terminals, not to the other switch terminal. This
explains how both sides of a given switch can show
leakage currents of either the same or opposite polarity.

There is no connection between the analog-signal paths
and GND. The analog-signal paths consist of an N-
channel and P-channel MOSFET with their sources and
drains paralleled and their gates driven out-of-phase to
V+ and V- by the logic-level translators.

LOGIC
(CARRIER)
V+ and GND power the internal logic and logic-level
translator and set the input logic threshold. The logic-
level translator converts the logic levels to switched V+
and V- signals to drive the analog switches’ gates. This
drive signal is the only connection between GND and
the analog supplies. V+ and V- have ESD-protection
diodes to GND. The logic-level input has ESD protec-
tion to V+ and to V- but not to GND, so the logic signal
can go below GND (as low as V-) when bipolar sup-
plies are used.

Increasing V- has no effect on the logic-level thresholds,
but it does increase the drive to the internal P-channel
switches, reducing the overall switch on-resistance. V-
also sets the negative limit of the analog-signal voltage.
FREQUENCY
The logic-level input pin, IN, has ESD-protection diodes
to V+ and V- but not to GND, so it can be safely driven
Y
to V+ and V-. The logic-level threshold, V , is CMOS/
IN
TTL compatible when V+ is between 4.5V and 36V
(see Typical Operating Characteristics).

Single Supply
The MAX4526/MAX4527 operate from a single supply
between +4.5V and +36V when V- is connected to
GND. Ob s e rve a ll of the b ip ola r p re c a utions whe n
operating from a single supply.
MAX4526/MAX4527’s internal capacitance and resis-
tance gradually impair performance. Similarly, imbal-
ances in external circuit capacitance and resistance to
GND reduce overall carrier suppression.
The carrier is applied as a logic-level square wave to
IN. (Note that this voltage can go as negative as V-.)
For best carrier suppression, the power-supply volt-
ages should be equal, the square wave should have a
precise 50% duty cycle, and both the input and output
signals should be symmetrical about ground. Bypass
V+ and V- to GND with 0.1µF ceramic capacitors, as
close to the IC pins as possible. Since the logic-level
translator/driver in the MAX4526 is faster than the one
in the MAX4527, it g ive s b e tte r re s ults a t hig he r
frequencies. In critical applications, carrier suppression
can be optimized by trimming duty cycle, DC bias
around GND, or external source and load capacitance.
__________Ap p lic a t io n s In fo rm a t io n
The MAX4526/MAX4527 a re d e s ig ne d for DC a nd
low-frequency-signal phase-reversal applications. Both
DC and AC symmetry are optimized for use with ±15V
supplies.
S ig n a l P h a s e /P o la rit y Re ve rs a l
The MAX4526/MAX4527 c a n re ve rs e the p ha s e or
polarity of a pair of signals that are out-of-phase and
balanced to ground. This is done by routing signals
through the MAX4526/MAX4527 and under control of
the IN pin, reversing the two signals paths inside the
switch before sending out to a balanced output. Figure
1 shows a typical example. The MAX4526/MAX4527
cannot reverse the phase or polarity of a single-
grounded signal, as can be done with an inverting
op amp or transformer.
In signal lines, balancing both capacitance and resis-
tance to GND produces the best carrier suppression.
6/MAX4527
Tra ns forme r c oup ling of inp ut a nd outp ut s ig na ls
provides the best isolation and carrier suppression.
Transformers can also provide signal filtering, imped-
a nc e ma tc hing , or low-nois e volta g e g a in. Us e a
center-tapped transformer or high-resistance voltage
divider to provide a DC path to GND on either the input
signal or output signal. This ensures a DC path to GND
and symmetrical operation of the internal switches.
